以下代码使用socket来实现异步调用，用来研究php socket异步调用、异步请求很不错。
例子：
复制代码 代码示例:
<?
/**
* php异步调用socket
*
*/
$host = "www.jb200.com";
$path = "/Report.php?ReportID=1";
$cookie = Session_id();
$fp = fsockopen($host, 80, $errno, $errstr, 30);
if (!$fp) {
print "$errstr ($errno)<br />n";
exit;
}
$out = "GET ".$path." HTTP/1.1rn";
$out .= "Host: ".$host."rn";
$out .= "Connection: Closern";
$out .= "Cookie: ".$cookie."rnrn";
fwrite($fp, $out); //将请求写入socket
//也可以选择获取server端的响应
/*while (!feof($fp)) {
echo fgets($fp, 128);
}*/
//如果不等待server端响应直接关闭socket即可
fclose($fp);
?>
